套管抗挤强度可靠性分析方法研究

Method study on reliability analysis of casing collapse strength

提出了一种新的套管抗挤强度可靠性分析方法——置信度与可靠性设计相结合的高精度小子样方法。与常规方法相比,本文方法计算结果精度高,并节省试样。

A new reliability analysis method for casing collapse strength was proposed as a high precision small sample method associating with degree of confidence and reliability designs. Compared with conventional method, the above method had high accuracy result and saved sample.
